DOOR BUFFER.

Application filed October 27,'1920, Seria1 No. 419,957. Renewed January 6, 1923. Serial No; 489,050.

To all whom it may concern:

Be it known that I, JAMES C. OLLARD, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented new and use ful Improvements in Door Bufi'ers, of which the following'is a specification.

The invention relates to a combined door stop and antirattle door buffer and dovetail for automobiles.

The object of the present invention is to provided a simple, practical and efiicient combined door stop, antirattle automobile door buffer and dovetail of strong, durable and comparatively inexpensive construction and adapted to be employed on door frames where the face or edge of the door frame is made plain or stopless, that is without a rabbet to receive the free edge or portion of the automobile door.

It is also an object of the invention'to provide an automobile door buffer ot-this character equipped with anchoring lugs adapted to be driven into the wood of the door frame and capable of maintaining the bufier alone in proper position and of relieving the attaching screws of bearing strain.

Another object of the invention is to provide a combined door stop and antirattle door buffer and dovetail composed of pin and socket 'interfitting elements or members adapted to prevent upward and downward movement of an automobile door and thereby stop any rattling of the same and at the same time provide means which will be yieldable and constantly forced against the door so as to prevent any inward and outward movement and resulting rattle.

With these and other objects in view the invention consists in the novel construction, combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawing, and pointed out. in the claims hereto appended, it being understood that various changes in the form, proportion and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the'advantages of the invention:

Figure 16 is a side elevation of a buffer illustrating another form of the invention.

Figure 17 is a front elevation of the same.

Figure 18 is a horizontal sectional view of the buffer.

Figure 19 is a vertical sectional view through the casing portion of the same.

Referring particularly to the form of the invention illustrated in Figures 1 to 9 inclusive of the drawings, the buffer which comprises a casing 1, a door engaging member 2 and a coiledspring 3 cooperateswith a buiier engaging spring 4 which, is secured to and carried by the door 5 of an automo bile and which is adapted to prevent vertical vibration of the door and the rattling which ordinarily results from such vertical move ment. The spring 4 is approximately U- shaped and is secured within a recess 6 of the door at the free edge thereof by means of a metallic strap 7 which is angularly bent as shown to fit the recessed portion of the door and which is secured to the same at the terminals of the strap7 by suitable fastening devices 8. The mounting of the buifer engaging spring in this manner prevents the piercing of the spring by screws or. other fastening devices and thereby avoids the weakening of the spring and increases the strength and durability of the same. The U-shaped buffer engaging spring has its terminal portions 9 curved or bowed as shown to provide a slightly flaring mouth or entrance and to present inner rounded or convex faces to the top and bottom of the buifer casing. This enables the buffer engaging spring to grlp the casing of the buffer and at the same time permits the casing to readily enter between the jaws or engaging side portions of the spring.

The casing 1 of the buffer which is formed from asingle piece of sheet metal is bent to form an inner or front wall 11 and an outer or rear wall 12, a connecting side wall 13 and top and bottom walls'14 and aninner side wall 15. The sheet metal is angularly bent at the sides andtop of the connecting wall13 and therfront wall 11 is provided with small projections 16' having" recesses 17 at the inner edges toreceive a projecting tongue or flange 18 of the inner side wall 15,. Thetongue or flange 18 is also provided atopposite sides with recesses or notches 19 which engage or interlock with the recesses or notches 17 of the front wall 11 and the tongue or extension 18 of the inner side wall is bowed or bent as indicated in Figure 9 of the drawing to enable it to readily pass through the space between he lugs or projections 16 and interlock with the notches or recesses 17. After the tongue or extension 18 has been placed in position it is straightened or flattened out to remove the bow or bend and the notched or recessed portions are thereby firmly inters locked with each other. The tongue or extension 18 is provided with a perforation to form an attaching ear or flange 1S and the top and bottom walls 14 are also provided with integral attaching ears or flanges 20,

each having-an integral right angle anchoring lug 20 located at the front edge at 0}): posite sides of the central ear 18 and adapted to be embedded in the wood,

The front wall 11 is provided with a circular opening 21 to receive the door engagingv member 2 which is in the form of. a tapered hollow cap. The hollow cap is-provided at the inner end with a stop flange 22 and the spring which has one end fitted i hin th doo I e a i g mem e i e gaged at the other end by a protuberance rmed l me inde ta i 511 t ea d wall 12, but any other suitable form of protuberance may of course be employed and the inner side wall which fits against the door frame 2 1 is preferably provided with an opening 25 to afford ready access to the spring and to permit the same and the door engaging member to be assembled after the casing has been completed. The door engaging member is forced inwardly and the spring is placed under compression bythe closing of the door and the said member and spring will hold the door against in ward and outward movement and prevent rattling ordinarily resulting from such movements of the door.

In attaching the buffer casing to the door frame the spaced tapering projecting anchoring lugs 20 are driven into the door frame and the screws or other fastening de vices are applied to the projecting ears. The tapering lugs will always maintain the buffer in proper position on the door frame and will relieveihe attaching screws of shearing strain. In Figures 10 to 13 inclusive ofthe drawings, is illustrated another form of buffer in which the casing 26 is open at the inner side, the inner side wall of the casing hereto-fore described being? omitted. The laterally extending cars 27 are provided with projecting right angle anchoring lugs 28 and the ear 29-is located between the lugs. The central lung 29 is formed integral with the front wall and th spaced tapering anchoring lugs are for-med integral with the top and bottom walls of the casing. The lugs are adapted to be driven into a door frame and perform the function of the lugs heretofore explained. The buffer casing 26 is also provided at the top and bottom with cars 27 In Figure 14; is illustrated a simpler form of buffer casing 31 designed for use on a door frame 3-2 having a rabbet 83 to form a stock for a correspondingly rabbeted door 34 as illustrated in Figure 15. of the drawings. The casing 81 is approximately [L shaped in horizontal section and is com posed of spaced walls or portions 35 and 36 and a connecting portion which is pros videdwith terminal attaching ears 37. The front wall or portion 35 is provided with lugs 38 which are embedded in the door frame as clearly shown in Figure 15, of the drawings. The door frame as indicated in Figure 15 of the drawings is recessed I to receive the buffer.

In Figures 16 to 19 inclusive ofthe draws ings, is illustrated another embodiment of the invention in which the side wall or attaching vmember 39 and the casing 40, have the spring 41 and the door engaging Inember 42 constructed from a single piece of sheet metal which is bent to form the. combined inner or rear wall and attaching plate 39 and the front, side and rear walls of the ng re e nt Wal of he as ns 40 is provided with an opening through which projects the door engaging member and which is provided with an integral extension 43 forming the top wall of the casing. The casing is open at the bottom wall to permit the ready assembling of the spring and the door engaging member.

The sheet metal employed in the construction of the various forms of the invention may be sheet steel or any other suitable ma terial and the buffer illustrated in Figures 16 to 19 inclusive of the drawings is designed to cooperate with the approximate spring herebefore described to provide a combined door stop and antirattle door buffer for automobiles. The engagement of the spring and the buflier provide an interlocking connection or device, the socket member being formed by the approximately U-shaped spring and the buffer constituting the interfitting or pin member of the device. The attaching member formed by the rear wall or side plate 39 is provided with upper and lower ears having apertures for the reception of screws and these ears have integral projecting tapering anchoring lugs 44 designed to be embedded in the door frame or casing and located at opposite sides of and spaced from a central ear or extension 45.

The front wall of the casing 40 is provided with an integral tongue 46 which is extended through a slot or opening 47 in the attaching member or side plate and the latter is also provided with a locking tongue or member 46 formed by partially severing a portion of the side wall or attaching member and adapted to be flexed from its normal position to permit the ready attachment of the tongue 46 and arranged when returned to its normal position for holding the tongue 48 of the front wall in engagement with the side plate or attaching member.
